摘要: 用溶胶-凝胶法低温合成多组分氧化物玻璃的详细工艺已有报导[1]。我们亦成功地用该法制备出了钕玻璃薄膜[2]和钕玻璃纤维[3]。本文报道利用此法低温合成LaAlO3超微粉末的研究结果。

Abstract: The ultrafine LaAlO3 with particle size of 10~50nm was prepared by sol-gel method, The firing temperature was as low as 750℃. The diameter of the ultrafine powder increases gradually with prolonging firing time and increases significantly with increasing firing temperature.

Key words: LaALO3 ultrafine powder, sol-gelmethod, preparation
